Specification of Letters Patent.

Patented May 18, 1915.

Application filed July 18, 1914. Serial N 0. 851,745.

To all whom it may concern:

Be it known that I, OSCAR KATZENBERGER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Single-Acting J amb-Hinge, of which the following is a full, clear, and exact description.

This invention relates to improvements in hinges and particularly to what are known as jamb hinges, and has for an object to provide an improved structure which may be adjusted so as to cause the door to swing shut or to cause the door to swing open.

Another object of the invention is to provide a spring hinge which is formed with an adjusting structure whereby the hinge may be set to swing open or to swing closed and in this movement utilize the unwinding tension when the spring moves the leaves of the hinge.

In the accompanying drawings :Figure l is a perspective view of a hinge embodying the invention, the same being shown applied; Fig. 2 is a section through the hinge shown in Fig. l, the same being taken approximately on the line 22; Fig. 3 is a section through Fig. 2 approximately on the line 33; Fig. 4 is a section through Fig. 2 on the line M; Fig. 5 is a view similar to Fig. 2 but with the adjusting parts reversed; and Fig. 6 is a section through Fig. 5 on the line 6-6.

Referring to the accompanying drawings by numeral, 1 indicates a wall of any desired structure and 2 a door of any desired structure. Associated with the wall 1 and door 2 is a hinge formed with leaves 3 and 4, the leaf 3 being formed with flanged apertured ears 5 and 6 which coact with a barrel 7 of the leaf 4:. It is to be observed that these parts are all made from stampings, though they could be made in some other manner, if desired. The leaf 3 is provided with a connecting shoulder or guard 8 that extends from the ear 5 to the ear 6 and against which the pin 9 presses when the spring 10 is under tension. The barrel 7 is provided with notches 11 and 12 designed to receive the pin 13 at dilferent times. The notch 12 receives the pin 13 when the various parts are set for normally holding the hinge closed, while the notch 11 receives the pin 13 when the parts are set for normally holding the hinge open. As shown in Fig. 2, a wearing washer 1a is provided for the encircling member 5 and a similar wearing washer 15 is provided for the ear 6. A rotatable disk 16 is arranged adjacent the washer 14:, this disk being pro vided with a suitable aperture for accommodating a pintle 17 and with an extension 18 having a slot 19 arranged therein for receiving the spring 10. A retaining and wearing washer 20 is provided below the ring 16 so as to provide a proper bearing for said ring.

Arranged at the bottom of the hinge is what may be called a plug or head 21 which is formed with a reduced extension 22 fitting into the barrel 7 and with a second reduced section 23 having a slot 24% arranged therein for receiving the lower end of the spring 10. The pin 13 extends through the notch 12 and also extends into the reduced extension 22 for connecting the head 21 with leaf 4. The spring 10 at the upper end is connected with the rotatable member 16 through the extension 18, while at the lower end the spring is connected with the extension 23, whereby the spring will not be maintained under tension unless pin 9 is inserted in one of the apertures 25 so that the pin may strike the guard 8 and wind the spring as the door 2 is opened. Of course in placing the hinge in position member 16 is rotated for bringing the spring under a certain tension, and this tension is merely increased when the door is opened. Upon releasing the door the spring naturally unwinds as it forces the door closed. In case more tension is desired on the spring, the ring 16 may rotate to a greater or less extent while the door is closed, and the pin 9 inserted into the aperture nearest the guard 8, whereupon there will be a continual pressure on the spring for causing the door to remain closed, and when the door is forced open this pressure or tension will be increased as the spring is wound. By this construction and arrangement it will be seen that the spring is wound in a natural way when the door is open and that it unwinds automatically when the door is released, said unwinding action causing the door to close.

When it is desired to adjust the various parts so that the door will normally remain open and will move to open position when released, the various adjustable parts are rearranged as shown in Figs. 5 and 6. From these views it will be observed that the rotatable ring 16 and associated parts are arranged at the bottom of the hinge, while the plug or head 21 and associated parts are arranged at the top of the hinge. When the pin 9 is arranged as shown in Fig. 5, the

same is used for urging the leaf 3 to open 7 position, and when arranged as shown in Figs. 1 and 2, the pin urges the leaf 3 to a.

closed position. In bringing the-spring 10 under tension, maintaining the leaf 3 in open position, the same is wound so as to tighten the coils in a similar manner to the way the spring is wound in Fig. 2, whereby the unwinding tension is used for holding the hinge open. By thus providing the parts described, means are presented which may be used so as to cause the spring 10 to act in the same way, either for holding the hinge open or for holding the hinge closed. In forming the leaves 3 and 4, the same are preferably provided with upstanding edges 26 and 27 respectively. This allows a small space to accommodate the pin 9 when the same is arranged as shown in Figs. 5, and 6.

In constructing the device the same may be made of any desired material, .but by reason of the use of the bearing members l t and 15, and the members and 21, the leaves 3 and 4, together with the barrels, associated therewith, maybe made from comparatively soft material such, for instance, as brass, while the bearing members and the associated parts just mentioned may be made from comparatively hard material so as to resist the usual wear.

It is to be noted that the action of the spring 10 may be reversed either before or after the hinge has been placed in the position shown in Fig. 1, so that if it is desired to maintain the door closed, thesame may be arranged for accomplishing that purpose and any time thereafter the parts may be adjusted for causing the door to be held open without removing the leaves 3 and 4 from the door and wall respectively.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A spring hinge, comprising a leaf formed with a barrel having a notch in each end, a second leaf formed with apertured ears, a coil spring in the barrel, an apertured head, provided with a reduced portion extending into one end of the barrel and having means to engage one end of the spring and a pin engaging one of the notches of the barrel, a rotatable and apertured disk provided with a reduced portion extending into the other end of the barrel and having means to engage the other end of the spring, said disk being provided with a plurality of radial openings, a pintle extending through the head, disk, barrel, and ears, and a pin adapted to be insertedin one of the radial openings of the disk, whereby provision is made for interchanging the head and disk to permit the leaves of the hinge tobe forced together or apart. g

Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
